When it comes to home improvement, selecting the right doors and windows is crucial. Aluminum alloy doors and windows are a popular choice due to their durability, aesthetic appeal, and functional benefits. However, to ensure you reap all these benefits, it’s essential to pay attention to several critical factors when purchasing and using these products. This article outlines the key considerations that consumers should keep in mind.

Importance of Brand Selection

One of the first steps in choosing aluminum alloy doors and windows is opting for branded products. Brand manufacturers adhere to stringent quality management systems, ensuring that the aluminum profiles are produced to precise standards and processed with advanced machinery. This guarantees dimensions and quality that small workshops often cannot match. Small workshops might use recycled aluminum profiles and manual processing, which can result in subpar products with inconsistent quality.

System Doors and Windows vs. Ordinary Doors and Windows

Another important consideration is choosing system doors and windows over ordinary ones. The wall thickness of the main profile of the aluminum alloy door should be at least 2mm, and for windows, it should be at least 1.4mm. Additionally, for thermal insulation, the use of PA66 with 25% glass fiber is recommended for broken bridge aluminum profiles. Avoid PVC thermal insulation strips, as they do not offer the same level of performance.

Glass Thickness Regulations

Selecting the appropriate thickness for tempered glass is vital for safety and durability. The following guidelines should be followed:

  • For tempered glass with a thickness not exceeding 5mm, the area of a single glass should not exceed 2㎡.
  • For tempered glass with a thickness not exceeding 6mm, the area should not exceed 3㎡.
  • For 8mm thick tempered glass, the area should not exceed 4㎡.
  • For 10mm thick tempered glass, the area should not exceed 5㎡.

These specifications help ensure the structural integrity and safety of the glass used in your doors and windows.

Safety Features

When using sliding windows on exterior walls, it is crucial to install anti-fall devices. These devices enhance the safety of the windows, preventing accidents. Additionally, the hardware accessories of aluminum alloy doors and windows are frequently used and play a significant role in the overall performance. High-quality accessories from reputable brands can improve wind pressure resistance and overall durability.

Installation Standards

The installation of aluminum alloy doors and windows is a critical aspect that directly affects their performance and longevity. The outer frame should be connected to the wall with a steel fixing plate, at least 20mm wide and 1.5mm thick. The distance between the fixing plate and the corner of the frame should not exceed 150mm, and the spacing between the middle fixing plates should not exceed 500mm. The fixing point of the fixing plate should be at least 50mm from the edge of the wall. Adhering to these standards ensures that the doors and windows are securely installed and stable.

Additional Safety Recommendations

While floor-to-ceiling windows can be visually appealing, they pose higher safety risks if not installed correctly. It is advisable to avoid using them unless necessary. Moreover, during extreme weather conditions, such as typhoons, ensure that all doors and windows are closed promptly. This helps prevent negative pressure from forming indoors, which could lead to safety hazards.


Choosing the right aluminum alloy doors and windows involves more than just aesthetics. By paying attention to brand selection, material specifications, safety features, and installation standards, consumers can ensure they make a wise investment. Prioritizing quality and safety will lead to long-lasting, reliable, and visually appealing doors and windows for any home.
